Looking for boy name ideas! Help?

Been researching baby names for years and now that I'm pregnant, I need help! Our favourite boy names happen to be popular ones, where as we've already agreed on Leona for a girl. I want help thinking of a name that can be used if we have a boy this time or next.

The only ones I would actually pick also happen to be the more popular ones (Evan, Marcus, Adrian, Liam, Ryan). So, just thought I would reach out and get some suggestions for solid names we may not have seen yet.

1-3 syllables maximum as our last name is a 5-syllable Spanish name. We like animal and nature-y names, something with a good meaning and can be from international origins. I like Hawaiian names, husband likes Irish and Swedish, so mostly anything goes. We like A, E, K, L, M, and R names.

And, btw we live in New Zealand so different trends here. Still curious to see what advice you have for me!

Oh I don't even know where to start. Thanks in advance for any ideas! <3

Leona is one of my favorite names. Lovely choice! I don't know how popular it is in New Zealand but it's fairly unusual in the U.S. so I think that should be taken into mind when picking a sibling's name.

My favorites from your choices are Adrian (although some may find it too feminine), Ethan (although it is very popular), Bran (can't find a fault except the fact that it is one syllable and a bit nickname-y), Keiran (maybe seen as too feminine again), and Forrest (pairs wonderfully with Leona).
